Structure and Magnetic and Magneto-Optical Properties of a New Cubic Ce3Sc2Ga3O12 Garnet Crystal with Heavy Ce3+ Concentration

“…Furthermore, their low laser damage threshold makes them unsuitable for high-power magneto-optical device applications. 9 Another commercially available magneto-optical crystal is terbium gallium garnet (Tb 3 Ga 5 O 12 , TGG). However, the communication wavelength of TGG is limited to the range of 500−1500 nm due to the low transmittance beyond 1500 nm caused by strong absorption of Tb 3+ ions.…”

“…Although ReIG crystals have large Faraday rotation angles in the mid-infrared region, the magnetic saturation due to their ferromagnetic properties limits the Faraday rotation angle to be flexibly adjusted. Furthermore, their low laser damage threshold makes them unsuitable for high-power magneto-optical device applications . Another commercially available magneto-optical crystal is terbium gallium garnet (Tb 3 Ga 5 O 12 , TGG).…”
